ELECTRIC VEHICLE WITH ELECTRICALLY-HEATED CATALYST DEVICE

摘要

PURPOSE:To enable the purification of exhaust gas from an internal combustion engine in a hybrid type electric vehicle with the internal combustion engine additionally provided at an electric vehicle driven by a motor by adding an electrically-heated catalyst device best suited to accelerate the purification of exhaust gas. CONSTITUTION:A hybrid type electric vehicle is provided with a travel motor 2, a battery 1 for supplying power to the travel motor 2, and an internal combustion engine 4. This electric vehicle is further provided with an electrically-heated catalyst device 7 for purifying the exhaust gas of the internal combustion engine 4, and a power supply 8 for supplying catalyst heating power to the electrically- heated catalyst device.
